[0001] . The object of the present invention is a dispensing device for the concurrent dispensing
of two or more fluids separately kept in a tank.
[0002] . In the field of dispensing devices, in particular intended for household purposes,
for example dispensing detergent fluids, there is the need of having devices suitable
for the concurrent dispensing of two or more fluids kept separately in a tank.
[0003] . Such need is generally related to the need of combining the two fluids only on the
surface to be cleaned, due to the deleterious effects that the combination of such
fluids would cause to the structure of the device.
[0004] . Or, such need is related to the need of keeping the two fluids separate into the
tank, for proper storage, combining.them upon dispensing or a few seconds before that.
[0005] . Some dispensing devices known in the field provide for the concurrent dispensing
of two fluids kept separate in a tank.
[0006] . However, such constructions are clearly derived from a simple coupling of two dispensing
devices, each suitable for dispensing a single fluid, actuated by a single trigger.
[0007] . An embodiment according to the description above is shown, for example, in document
EP0715899. Moreover, such devices are disclosed in documents WO 97/27121 and DE 197
38 039.
[0008] . There is therefore the need of having a dispensing device for the concurrent dispensing
of two or more fluids kept separately in a tank which should be designed for such
precise purpose and which should therefore provide for a limited number of components
and an optimum operation.
[0009] . Object of the present invention is that of providing to the realisation of a dispensing
device which should meet the above requirements and at the same time overcome the
disadvantages mentioned above with reference to the prior art.

[0081] . Preferably, said counter frame arm 140 projects from said counter frame plate 132
from the same side as said projections 134a, 134b.
[0082] . Moreover, counter frame 130 exhibits an annular counter frame wall 144, projecting
from said counter frame plate 132 from the same side as said projections 134a, 134b.
[0083] . According to a preferred embodiment, the swirling means 200 comprises a first tubular
swirling element 202a and a second tubular swirling element 202b (figures 9a, 9b,
10a, 10b and 11).
[0084] . Each tubular swirling element 202a, 202b comprises a connecting portion 204a, 204b
and an active portion 206a, 206b.
[0085] . Said active portion 206a, 206b exhibits an inside arm 208a, 208b integral with the
respective connecting portion 204a, 204b by a swirling plate 210a, 210b, provided
with arm openings 212a, 212b.
[0086] . At the free end, each inside arm 208a, 208b exhibits at least one swirling projection

[0087] . Said swirling projections are preferably arranged circumferentially at the free end
of the swirling arm, spaced out by swirling notches 216a, 216b.
[0088] . Moreover, said swirling means 200 comprises a mask 220 provided with connecting walls
222a, 222b to said tubular swirling elements 202a, 202b.
[0089] . Moreover, said mask 220 exhibits respective swirling walls 224a, 224b, each provided
with a dispensing opening, 226b.
[0090] . In an assembled configuration of the dispensing device 1, the first pipe 10a and
the second pipe 10b are respectively inserted in the first thorough opening 30a and
in the second thorough opening 30b of the circular plate 29 of the closing means 20.
[0091] . Said plate is arranged inside said closure 22, preferably at the end of the threaded
portion 26, adjacent the snap mechanism 28.
[0092] . The venting membrane 32 is made integral with frame 62, preferably at the surface
of the connecting plate 88 of frame 62 that faces the interior of the containment
chambers.
[0093] . Preferably, said venting membrane 32 is welded to the connecting plate 88 so as to
cover the venting openings 89 presents in said plate.
[0094] . Frame 62 of the pumping means 60 is arranged on the circular plate 29, so that the
connecting plate 88 of said frame is connected to closure 22 by the snap mechanism
28.
[0095] . The first pipe 10a is in fluid communication with the first tubular intake element
74a and the second pipe 10b is in fluid communication with the second tubular intake
element 74b.
[0096] . Membrane 100 of the pumping means 60 is associated to frame 62.
[0097] . In particular, the membrane plate 102 is adapted for being coupled to the frame plate
64 and surrounded by the connecting wall 90 projecting from said frame plate 64.
[0098] . The pumping elements 104a, 104b are respectively inserted into the insertion openings
86a, 86b of the frame plate 64.
[0099] . Correspondingly, the annular walls of the valve delivery means 108a, 108b of membrane
100 couple with the respective delivery chambers 68a, 68b of frame 62.
[0100] . In particular, said coupling makes rings 114a, 114b of the cap elements 112a, 112b
introduce into the respective delivery openings 70a, 70b, insisting on the respective
annular delivery opening walls 72a, 72b.
[0101] . Correspondingly, the annular walls of the check valve means 120a, 120b couple with
the respective intake chambers 80a, 80b.
[0102] . In particular, each lip 118a, 118b of membrane 100 couples with the respective
intake opening 82a, 82b, abutting against the respective intake opening wall 84a,
84b.
[0103] . The counter frame 130 is adapted for associating to frame 62 so that membrane 100
appears as an intermediate element blocked between said frame and said counter frame.
[0104] . In particular, the connecting wall 90 of the frame plate 64 couples with the annular
wall of the counter frame plate 144, for example with a snap connection.
[0105] . Projections 134a, 134b of the counter frame 130 are arranged at the check valve means,
whereas the respective projections 136a, 136b penetrate, at least partly, into the
volume defined by the pumping elements 104a, 104b.
[0106] . Partitions 122a, 122b of membrane 100, coupled with the membrane plate 102, with
the pumping elements 104a, 104b and with the counter frame plate 132, define a first
pumping chamber and a second pumping chamber, separate from one another.
[0107] . In particular, said first pumping chamber and said second pumping chamber are separate
because said flow partitions after assembly insert between projections 134a, 134b
of the counter frame 130.
[0108] . Said pumping chambers respectively are in fluid communication through a duct called
intake duct, with the first containment chamber and the second containment chamber
of the tank.
[0109] . Preferably, said intake ducts comprise said tubular intake elements 74a, 74b of frame
62 and said pipes 10a, 10b.
[0110] . Between said pumping chambers and said containment chambers, along said intake ducts,
there are provided said check valve means 116.
[0111] . Moreover, said pumping chambers respectively are in fluid communication through a
duct, called delivery duct, with the exterior of the dispensing device.
[0112] . Between said pumping chambers and said environment outside the dispensing device
1, along said dispensing ducts, there are provided said valve delivery means 106.
[0113] . In particular, the cap elements 112a, 112b of said valve delivery means 106 are respectively
inserted into the annular counter frame walls 138a, 138b of said counter frame.
[0114] . The counter frame arm 140, protruding from the counter frame plate 132, is adapted
for hinging trigger 42 of the actuation means 40.
[0115] . In particular, the hinging pin 52, carried by arm 50 of trigger 42, is operatively
coupled with the hinge seat 142 of the counter frame arm 140, realising a hinge for
said trigger.
[0116] . After assembly, the actuation means 40 is arranged in suitable position for affecting
the pumping means for fluid dispensing.
[0117] . In particular, said actuation pins 48a, 48b of the actuation portion 46 of trigger
42, can abut against the respective pumping elements 104a, 104b of the pumping means
60.
[0118] . The free end of the tubular delivery elements 66a, 66b of frame 62 is associated
to the respective tubular swirling elements 202a, 202b.
[0119] . In particular, the connecting portion 204a, 204b of said tubular swirling elements
associate to said free ends, for example by a snap connection.
[0120] . Preferably, said tubular delivery elements are moved in abutment with their free
end with the swirling plates 210a, 210b of said swirling means.
[0121] . Said tubular delivery elements 66a, 66b remain in fluid communication with the exterior
of the dispensing device thanks to the openings of arm 212a, 212b provided on each
swirling plate 210a, 210b.
[0122] . Mask 220 of the swirling means 200 is adapted for being associated to said tubular
swirling elements 202a, 202b.
[0123] . Preferably, the connecting walls 222a, 222b of said mask 220 are coupled the active
portion 206a, 206b of the tubular swirling elements 202a, 202b.
[0124] . The swirling walls 224a, 224b of mask 220 abut against the swirling projections 214a,
214b of the inside arms 208a, 208b.
[0125] . The volume comprised between the inside arm 208a, 208b, the active portion 206a,
206b and the swirling plate 210a, 210b of the tubular swirling element 202a, 202b
and the swirling wall 224a, 224b of mask 220 defines an intermediate chamber.
[0126] . The volume comprised between the free end of the inside arm 208a, 208b, the swirling
projections 214a, 214b of the tubular swirling element 202a, 202b and the swirling
wall 224a, 224b of mask 220 defines an end swirling chamber.
[0127] . Said intermediate chamber and said end swirling chamber are in fluid communication
by notches 216a, 216b of the inside arms 208a, 208b.
[0128] . In other words, the delivery duct between the pumping chambers and the outside environment
comprises a swirling duct, said swirling duct comprising an intermediate chamber and
an end swirling chamber, in fluid communication with the outside environment through
a dispensing opening 226a, 226b of mask 220.
[0129] . Cover 300 is associated to said dispensing device for covering at least partly said
pumping means and/or for facilitating an ergonomic grip of the device by the user.
[0130] . In a first operating configuration, the dispensing device is in a rest configuration
wherein the pumping elements 104a, 104b are in a non-deformed configuration, that
is, in a configuration wherein the pumping chambers exhibit a maximum volume.
[0131] . In the normal use of the dispensing device 1, the user grips said device, for example
arranging the rear side of cover 300 in contact with the hand's palm and the fingers
on the handling portion 44 of trigger 42.
[0132] . The valve delivery means 106 and the check valve means 116 are in a closed configuration.
[0133] . By actuating trigger 2, hinged, its actuation portion 46 affects the pumping elements
104a, 104b at the same time, deforming them.
[0134] . In other words, said pumping chambers shift from the maximum volume to a volume smaller
than the maximum volume, for example a minimum volume, corresponding to the maximum
rotation of trigger 42.
[0135] . The first and the second fluid, separately held in the first pumping chamber and
in the second pumping chamber, through the action of the trigger and the deformation
of the pumping elements, generate a thrust that moves the valve delivery means in
an open configuration, whereas the check valve means are forced into a closed configuration.
[0136] . In other words, the thrust of the fluids acts on the cap elements 112a, 112b of the
valve delivery means, making them collapse.
[0137] . In particular, ring 114a, 114b of said annular cap elements moves away from the delivery
opening 68a, 68b of frame 62, placing said pumping chambers in fluid communication
with the outside.
[0138] . The first and the second fluid flow through the dispensing duct to the outside, preferably
flowing also through said swirling duct.
[0139] . In the swirling duct, said fluids are separately subject to swirling through the
passage through notches 216a, 216b of the inside arms 208a, 208b.
[0140] . The fluids are therefore separately dispensed, for example on a surface to be cleaned.
[0141] . At the same time, the thrust to which the fluids held in the pumping chambers are
subject pushes lips 118a, 118b of the check valve means against the intake openings
82a, 82b of the intake chambers 80a, 80b, preventing the reflow of said fluids towards
the tank containment chambers.
[0142] . By releasing trigger 42, the pumping elements 104a, 104b, that exhibit elastic properties,
return to the non-deformed condition.
[0143] . Said elastic return of the pumping elements causes a whirlpool action inside the
pumping chambers which brings the valve delivery means back to a closed condition
wherein the cap elements 112a, 112b close the delivery openings 70a, 70b.
[0144] . In other words, the pumping chambers are not in fluid communication with the outside
environment, since the dispensing duct is cut out.
[0145] . At the same time, said whirlpool action moves lips 118a, 118b of the check valve
means away from the intake openings 82a, 82b, placing the pumping chambers in fluid
communication with the fluid containment chambers.
[0146] . Through said pipes 10a, 10b, the first and the second fluid are sucked by the respective
containment chambers of the tank to the respective pumping chambers of the dispensing
device 1.
[0147] . When the pumping chambers are restored to the normal volume, the whirlpool action
stops and dispensing device returns to the rest configuration.
[0148] . It is clear that when the device is first used, it is necessary to repeatedly press
trigger 42 to fill the pumping chambers with the fluids coming from the containment
chambers.
[0149] . The venting membrane 32, the venting openings 89 and openings 30c, 30d of the circular
plate 29 made of a foamed material are a preferred example of the venting means, adapted
for allowing the gas venting from the containment chambers to the outside of the device.
[0150] . In particular, said venting means allow degassing the containment chambers following
the possible production of undesired gases released by said fluids, as well as a passive
venting.
[0151] . During operation, the trigger action on the pumping elements is opposed by the structure
of the dispensing device 1 which provides for membrane 100 arranged in intermediate
position between frame 62 and counter frame 130.
[0152] . Said trigger action is opposed by the connection between said frame and said counter
frame and at the same time, by the connection between the counter frame and the trigger
itself.
[0153] . In other words, the action of trigger 42 tends to make membrane 100 come out of frame
62. This action is opposed by the connection between frame and counter frame and at
the same time, the connection of the counter frame arm 140 with the trigger itself.
[0154] . Said counter frame arm - trigger connection pushes the counter frame towards the
frame and thereby membrane 100 towards the latter.
[0155] . Frame 62, during the operation of the device, keeps membrane 100 into position so
that the action of trigger 42 on the pumping elements 104a, 104b is effective.
[0156] . At the same time, it exhibits both the tubular intake elements 74a, 74b, and the
tubular delivery elements 66a, 66b.
[0157] . Said elements, that respectively realise intake ducts and delivery ducts, develop

[0158] . Membrane 100, made of a deformable elastic material, exhibits both the pumping elements
104a, 104b, and the check and delivery valve means and the partitions for realising
separate pumping chambers for the first and the second fluid.
[0159] . In a further embodiment of the dispensing device 1, the fluids are separately held
in the respective containment chambers of tank 1 and dispensed separately in a mixing
chamber wherein they are mixed before they are delivered outwards (figures 12, 13,
14a, 14b, 15a, 15b).
[0160] . Hereinafter, reference shall be made only to the peculiar features of the above embodiment,
references to same components being the same as the description above.
[0161] . In said embodiment, the dispensing device 1 comprises swirling means 400 comprising
a mixing element 402 provided with tubular connecting elements 404a, 404b adapted
for associating with the free end of the tubular delivery elements, 66b of frame 62.
[0162] . Said tubular connecting means exhibit, at a side opposed to the connecting end with
said tubular delivery means 66a, 66b, respective ejection openings 406a, 406b, preferably
obtained in the front wall 408 of a lining element 410.
[0163] . Said front wall 408 further comprises one or more swirling projections 412 separate
from one another and preferably arranged circumferentially.
[0164] . In a preferred embodiment, said projections 412 are flush with the surface of the
front wall 408.

406b that allow the fluid communication with the tubular delivery elements 66a, 66b,
and the dispensing opening 418 that allows the fluid communication with the outside
environment.
[0170] . The fluids to be dispensed, separately, are pushed, during the dispensing step, inside
the tubular connecting elements 404a, 404b, from which they exit into the swirling
chamber.
[0171] . Into said chamber, the fluids mix both freely and by action of the swirling realised
by the projections of the front wall.
[0172] . From the swirling chamber, the mixed fluid is dispensed out of the dispensing device.
[0173] . Notches 420a, 420b realised into the swirling wall 417 and the front wall 408 of
the mixing element 402 form a preferred example of means for opening/closing device

[0174] . In a first operating configuration of said means, mask 414 is in a first open position,
wherein notches 420a, 420b are overlapped, at least partly, to openings 406a, 406b
of the mixing element 402.
[0175] . In said position, openings 406a, 406b are in fluid communication with projections
412 by said notches 420a, 420b, so the fluids come out.
[0176] . In a second operating configuration of said means, mask 414 is in a second closed
position, wherein notches 420a, 420b are not overlapped to openings 406a, 406b of
the mixing element 402.
[0177] . In said position, openings 406a, 406b are not in fluid communication with projections
412, so fluid dispensing is prevented.
[0178] . Unusually, the dispensing device for two or more fluids separately kept in a tank
according to the present invention exhibits a reduced number of components.
[0179] . In other words, the dispensing device according to the present invention exhibits
components each having multiple functions, so as to reduce the number of necessary
components.
[0180] . Advantageously, the membrane is made of a deformable elastic material and realises
means for changing the volume of the pumping chambers, elastic return means and, coupled
with the counter frame, it delimits said pumping chambers.
[0181] . At the same time, said membrane integrates check and delivery valve means.
[0182] . Advantageously, moreover, the frame comprises the tubular delivery and intake elements
and effectively supports the membrane for opposing the trigger action on the pumping
elements.
[0183] . A further advantages is that the device is provided with intake and delivery ducts
having extension along incident directions, preferably perpendicular, in order to
